Most of the leaves on Dischidia pectinoides are small leaves around 3/4 of an inch long by 3/8 of an inch wide, but on occasion they develop these monster ‘Ant Leaves’.  This Dischidia has developed a symbiotic relationship with with ants becoming an evolutionary marvel.  The ants will colonize these giant leaves that form hollow spheres which are inhabited by ants.  In turn the waste products from the ants fertilize the plant.  These clam-shaped, special leaves can be 3.5 inches long by 2.5 inches wide and 2 inches thick which can provide generations of ants with a completely waterproof home.
